Study Notes
Vertical Translations
- F(x) + c: Indicates a vertical translation upward by c units.
- F(x) - c: Represents a vertical translation downward by c units.
Horizontal Translations
- F(x + c): Signifies a horizontal translation to the left by c units.
- F(x - c): Denotes a horizontal translation to the right by c units.
Reflections
- -f(x): Demonstrates a reflection of the graph over the x-axis, reversing the y-values.
- F(-x): Represents a reflection over the y-axis, reversing the x-values.
Vertical Transformations
- Af(x) with A > 1: Indicates a vertical stretch, making the graph taller.
- Af(x) with 0 < A < 1: Signifies vertical compression, resulting in a squished graph when A is a fraction.
Horizontal Transformations
- F(ax) with A > 1: Indicates horizontal compression, squeezing the graph closer together.
- F(ax) with 0 < A < 1: Represents a horizontal stretch, causing the graph to spread out.
